IP
settings pane of Search parameters
screen of Search My Network provide settings for IP search.
You are allowed to specify IP addresses, IP ranges and computer names
here, and the search will be performed only on the specified servers.
Multiple items should be separated by semicolon ;.
IP ranges should be specified using dash -
symbol (either with leading/trailing spaces or not). For example, the
following is a valid value for IP settings text:
192.168.0.1 - 192.168.0.100; 192.168.1.233; serv23; workstation20.
As a result, the search will be performed on servers with the specified
IPs and additionally on computers serv23 and workstation20.

Warning:
Using IP settings pane it is possible to specify very broad IP
ranges that may result in long-time searches (e.g. the range 192.0.0.0
- 192.255.255.255 covers 16777216 IP addresses). The program does not
have any limits for this, so be sure to specify IP ranges carefully.
